Hey guys, I will soon be setting up a 300 gallon Rubbermaid stock tank as an indoor pond but I dont like that it is black and I dont think they come in any other color. I was thinking of changing the color to blue so that the fish are more easily viewed. Is there some kind of epoxy out there that is blue and can stick to the tank also fish safe? Thanks for the help. I will be using my 55 as a filter and maybe a pressurized canister filter with a UV sterilizer I saw one at a home improvement store for about $170 and it says it can filter a 600 gallon pond. Just a thought--- all the money I have spent on wet/drys and HOB filters these pond filters and pumps at these improvement stores seem pretty cheap but are they just as good :-? Anyways when I get a new computer that I can hook my camera up to I will show some pics.
